Question

Quizplus · Accepted Answer

The pitch of a sound is determined by the frequency of vibrations of air molecules. Higher frequency vibrations produce higher pitched sounds, while lower frequency vibrations produce lower pitched sounds.

Option B) is incorrect because the amplitude of a sound wave determines its volume, not its pitch.

Option C) is incorrect because decibels (dB) are a unit of measurement for sound intensity or volume, not pitch.

Option D) is partially correct as it includes option A, but option B is incorrect.

Option E) is incorrect because option C is not correct.
